The petroglyphs at Kjøbenhavnerbukta is found at Kvernevik in Stavanger, and are sometimes also refered to as “helleristningene ved Kvernevik”. It’s a small field with large ship figures found next to the Kvernevik Ring road.
The figures are dated to the Nordic Bronze Age, like all the petroglyphs in Stavanger and Rogaland.
